I've had chickens for about a month now. I noticed early today (like before noon) that Nelly, my speckled sussex hen, was missing. This is not highly unusual; we let them out when the sun comes up, and they are free range so they sometimes roam away from the barn, but Nelly typically does not. Anyway, during the day I was away, but when I came home and was ready to lock the coop at sunset, I was surprised to find that Nelly was still gone. I searched for an hour and found her body, or what was left of it. It kind of looks like something pulled her innards out and ate the meat off her legs. Her head is still there and untouched, still connected to the body. Feathers are scattered around but not a lot of them. What I want to know is, what do you think killed her, and how can I trap it/kill it to keep the rest of my flock safe? Please help! I'm still very new at this and am very upset. I don't want to lose any of the other chickens I've come to think of as pets!
